Upstream source description

The B2BKing — Ultimate WooCommerce B2B and Wholesale Plugin — Wholesale Prices, Bulk Order Form & More WordPress plugin before 5.2.40 does not verify that a role selected during registration is one actually offered on the registration form, allowing unauthenticated users to assign themselves to restricted B2B customer groups and to skip the manual account-approval workflow during self-registration.
